The widget runs fully on your storefront with no extra server calls. Setup is simple: one wizard per product handles metafields and the hidden variant for you. Built for curtains, blinds, glass, fabric and any cut-to-size product.

• Works offline on the storefront, totals calculated in the browser, no extra call
